I used a product from a local company called ozicozi. It is supplied in a roll and the application process is similar to Rob's explanation in the previous post. The chap I spoke to was very helpful and even sent a tempate with the material that he had done for someone with an "original" Cobra. I just cut mine with scissors. Here is the website:

The product is reasonably easy to apply as it strectches very well around curves. However, I had some problems with the concave lip on the wheel arch on my Harrison. It is sharp enough that I couldn't get the material to stick. A more experienced fitter may be able to manage this. As a result, I have a good demonstration of the effectiveness of the product. After 12000km, the paint not covered by the film is peppered with stonechips.
Another consideration is a product from Goop! This is more of a temporary protection (up to 6 months) that can easily be peeled off. The finish is rougher than the 3M type film, but it can be applied to any shaped surface. More like something that could be used for a longer trip e.g. Nationals, Summernats, Wintersun etc. There is a reference to it in the March 2009 edition of Street Machine (p54) that sounds positive.
